LHVIEKILN.

SPECIFICATION forming part of Letters Patent No. 299,313, dated May 27, 18a/i.

I Application filed March 4, 1884. (No model.)

o all whom, it may concern.:

Be it known that I, BERNHARD ALBERs, of Conception, in the county of Nodaway and State of Missouri, have invented a new and useful Improvement in Limekilns, of which the following is afull, clear, and exact description.

This invention pertains to improvements iu limekilns; and it consists of the detailed construction and combination of parts, substantially as hereinafter more fully set forth, and pointed out in the claim. u

Reference is to be had to the accompanying drawings, forming a part of this specilicatiomin which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of my improved limekiln. Fig. 2 is a front side elevation. Fig. 3 is a sectional elevation on the line m x of Fig. l, and Fig. 4 is a sectional elevation on the line 3,/ y of Fig. I.

At a suitable distance above the lloor a of the kiln for a practicable ash-pit, b, I arrange a lire-grate, c, which I make of considerably smaller area than the area of the burningchamber d, with marginal shoulders e of the walls of the kiln, converging the chamber to the area of the grate, thus limiting the area of the grate, so that more eifective combustion is caused of the quantity of fuel mixed with the limestone than is obtained where the fire bed extends throughout the whole area of the chamber and lies on the iioor of the kiln,

which makes such sluggish combustion that the fuel is consumed without producing the required intensity of heat, the fuel occupying so much area that too much area is allowed for air to enter, which keeps the temperature too low. An opening, f, is to be madethrougli the wall of the furnace above the iiregrate, for enabling the fire to be attended to and replenished when required, and a door, g, Will be attached for closing it.

I arrange the grate c on the ledges h of the shoulders e, so that it can be taken out readily for removing it when burned out, and 'for changing it from one kiln to another.

I am aware that, broadly, in a limekiln it is not new to contract the base of its chamber and to employ a iiregrate of less area than the body of said chamber; and that, broadly, it is old to support the grate removably.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t- The kiln having the base of its chamberprovided with rounded convergent shoulders c, said chamber being provided below the outer edges of said shoulders with ledges h, upon which is supported a firegrate, c, substantially as shown and described, and for the purpose set forth.

BERNHARD ALBERS.
